TYPE-VIRITING MACHINE.

eas es To all whom it may concern: v

Be it known that L; EDWIN E. BARNEY, citizen or" the United. States, andresident of Syracuse, in the county of Onondaga and Stategoit New York,have invented certain new; and useful. Improvements in Typel l riting.Machines, of which the following is a specification.

My invention relates to typewriting'machincs and more particularly tothe method of audincans for uniting hanger arms.

Great diliiculty has been encountered heree totore in obtaining andmaintaining the proper adjust in cut between the hanger arms Oi a typebar and between the bearings 01: the type bar. Various methods have beenemployed for connecting the hanger arms to retain "the hearings properlyadjusted, such, for instance, as ordinary rivets, shouldered rivets,combined right and left-hand screws between the hanger arms and headedscrews threaded at one end into a hanger arm and headed andunt-liireaeled at the other.

The screw connections wereemployed pri-- marily as adjusting means foreffecting a relative adjustment between the hanger arms. All of thesemeans, however, are open to objection and have not proved reliable.Connecting the hanger arxis by rivets involves various objections. insome cases the desired adjustment between the hanger arms and thebearings could not always be obtained in the first instance, but it wasnecessary in order to get the best re sults to first unduly tighten-thebearings, form the heads of the rivets and then afterward loosen up thebearing until'the type bar'was sufficiently tree to turn easily.

side from the above disadvantages from the use of rivets they onlyprodded, in some instanccaior preventing the hanger arms tron. springingoutwardly and by their use s, and in no case ion of the hearings be ccant? unnerved. Moreover, in some instances. heading; up oi the rivetsjustment of thebearings could be attained only through an adjustment ofthe screw.'

screws, the adjustment of the hearings mainly depended upon the screws.Then;

again such screws made no provision for pre-l ventmg an inward movementof the hanger arms. They provided only against the arms springingoutwardly away from each other.

threaded into a hanger arm at one end was employed. Turning the screwsin such constructions changed the relation of the arms of the hanger andaffected the bearings of the type bar. I

The ma n object of my invention to overcome the above and otherdifiiltzultics heretofore encountered and to provide a simple andeflicientmethod of and means for uniting hanger arms while they aremaintained. in adjusted relation. with the type bar in placeand withoutdisturbing such adjustment and for maintaining the adjustment of thearms while the hanger is in use. i

To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations of devices to be hereinaf er described and particulariypoint ed out in the appended claims.

In. the accompanying drawings, Figure 1 is anlenlargcd detail side viewof a type bar and hunger made in accordance with my invention. mldig. 2is a front elevation of the same with parts sectioned away. Fig. 3 is afragn'ientary vi'ew'showing a machine or mechanism for carrying out themethod" forming the subject-matter of the present invention, the viewillustrating a type bar and hanger 1n lace in the machlne and the beunderstood that various styles of type bars and bifurcated hangers maybe used.

The type bar 1 is provided with trunnionlike concd pivots 2 which arereceived in hunger arms connected by itsthreadcd conthreaded end in atapped opening in a seg-.

ment 9. In making the hangers they are pr ferably formed from a blankwith pivoted bearings therein and holes are pierced .therein which are aterward tapped for a threaded tie rod. Th hanger is then formed andfolded substantially as shown in the drawings with the typebar seated inthe bearings between the hanger arms, the holes for the tie rod lacingbrought into alinement.

The hanger is adjusted to a centering form (not shown)=-upon asemi-automatic machine and is received between two hand operated jaws l0(.llig. 3) of a vise-like clamp forming partof the machine. These jawsare closed over the bearing ends of the hanger so that the exactrelation of the hanger arms and bearings for the type bar is providedand maintained. This adjustment of the type bar and hanger in themachine brings the'openings for the tie rod into registration with a tap11 and with a wire 12. The \wire 12 is secured in a rotary chuck 13 andis adapted to pass through a fixed die 1% by which threads 15 are outalong the, wire when the: chuck is rotated.

The operator first mo s a treadle which releases the rotating/tap 11 andcauses'it to move in the: direction of the arrow 16 and to pass throughthe registering tie rod openings in the hanger and to tap the openingsin bothjhanger arms at a single operation so that the threads tapped inone hanger arm are as though they were a continuation of those tapped inthe other hanger arm in order that a .screw, the threads of which extendin one direction, may pass through and properly co-act with thethreadsin both of the hanger arms without' disturbing the adjustment of.cither ljianger arm. After the tap haspassed through both of theregistering openings in the hanger arms the rotation of the tap isreversed and it is .moved in the direction of the arrow 17 andWithdrawn. from the hanger. Simul aneously with the withdrawal of the tabll the wire 12 is rotated pass .it throughthe staby the chuck 13 ttionary thread cut ing die 14 and to feed 'the screw threaded rod in thedirection of thc-arrow 18, the feed of the wire being suitably timed tofollow up the receding tap and to thread itself through the. tappedholes in the hanger arms until the free end of the wire projectsslightly beyond the lefthand wall of the hanger in Fig. 3. The wirel2ceases to rotate at this point and during the stop motion of the wirerod two parallel saws 19 and 20 move transversely of the axis of therod, one to sever the projecting end close to the hanger and the otherto sever the threaded tie rod from the body portion of the wire as shownin Fig. The iws then swing back to the position shown inFig. 3 and thedirection of rotation of the wire 12 reversed to draw the projectingthreaded end back through the threading die 1-1 in the direction of thearrow 21 to remove any bur caused by the saw 19. This leaves the tie rod22 of uniform diameter throughout and also threaded for its wholelength. Each end of the tie rod extends slightly beyond its associatehanger arm as shown in Figs. 2 and The operator then releases the jaws10 and removes the hanger with the type bar mounted in place and thehange 1 arms properly united by the tie rod. The act of threading thetie rod through the tapped openings in the-hanger arms in no mannerdusturbs the adjustment of the hanger arms provided by an adjustment ofthe jaws 1.0. The hanger with the bearing tacos in the hanger armsproperly adjusted with ref erence to the pivot of the type bar isclamped before the threaded rod 12 is threaded into the tapped openingsand this adjustment is maintained during the act of connecting thehanger arms and is not afterward disturbed, and there is no liability ofa derangement of the adjustment in the subsequent use of the type bar inthe typewrit-ing machine.

Thus it will be understood that the threads of the tie rod, allextending in the same :direction, cause the two arms of the hanger toact as check nuts or, in other words, each threaded opening in a hangerarm effects a checking or counterbalance on the other to prevent arotation of the screw in its tapped openings in either direction.Otherwise stated, if one hanger arm through an outward tension tends torotate the screw tie rod in one direction, the opposite arm, which musthave the same degree of tension, tends torotate the screw threaded tierod in the opposite direction. It will-be understood, however, thatevenit this headless threaded tie rod should turn inits tapped openingsnally through the tapped openings but the hanger arms yvouldstlllbemaintaincd properly spaced apart. There is no necessity in thisconstruction of upsetting the ends of the tie rod because there isnotel'idency for the threaded wire to turn in its tapped openings and itis not intended that the tie rod should in any manner effect anadjustment between the hanger arms, this adjustment being provided inthe first instance before the tie rod is inserted in place. It is notordinarily intended to readjust the hanger. In exceptional cases,however, where the bearing loosens up from wear and re-adjustment isnecessary, the adjustment can be eli'eeted without the mutilation of thescrew by removing the hanger from the machine and slight l compressingthe projecting erds oi the threaded tie rod between the jaws of a Visewithout exerting any direct pressure upon the hanger arms themselves.This will be sullieient to move the hanger arms toward ea h other tocompensate for any wear at the bearings without loosening the connectionbetween the hanger arms.

l t will be understood that the threaded tie rod resists both inward andoutward. movement ol the hanger arms and forms an ellieienl lie orconnection between the hanger arms. It has been found. in practice that.the present construction. will resist a pressure of more than twice theamount of a rivet connection between the hanger arms.

Thus it may be assumed that a riveted hanger subjected to a pull oflil'ty pounds at the rivet will cause a loosening up of the hearing. Thethreaded eonnectitm of the present construct ion will resist a onehundred pound affording a. loosening of and operative to preventexpansion of said arms, the threads of the screw and of the openingsextending in one direction only.

2. T he herein described method of uniting a hit'ttrfatetl hanger and atype bar having a pivot which consists in adjusting the hanger arms intheir proper relation to said pivot by forcing said hanger arms towardeach other, holding said arms in their ad justed positions, tappingopenings in said hanger arms while thus held, and then threading asingle tie-rod through said tapped openings while the said arms arestill maintained under compression and in adjusted relation to thepivot.
